The aerobic energy system uses glucose, fat, and protein as fuel sources. Glucose and fat are the primary sources of energy, while protein can be used as a last resort if the other sources are depleted. This system requires oxygen to efficiently produce energy through the process of cellular respiration.
fat
The primary disadvantage of using fat as fuel during endurance exercise is that it is not entirely clear where the fat used comes from. It is not certain whether it is adipose tissue, which the body has plenty of, or intramuscular triglycerides that are stored in muscle fibers.
2 carbon sub-groups derived from fat (or sugar if insulin is present).
The primary accent is on the third syllable: in-de-FAT-i-ga-ble.
yes
The primary fat in ice cream is milk fat, a saturated fat derived from milk.
Carbohydrate Fuel Factor: 4kcal/g Fat Fuel Factor: 9kcal/g Protein Fuel Factor: 4kcal/g Carbohydrates are the preferred source of energy and used quickly. Fat is then a backup source of energy when carbohydrate fuel availability is insufficient. Protein fuel is used when both carbohydrate and fat available fuel is inadequate; however, it is a less efficient back up source.
Yes, muscle glycogen is a primary fuel source for endurance exercises such as long-distance running and cycling. It is stored in muscle tissue and can be rapidly broken down to provide energy during prolonged, low to moderate intensity activities. However, for longer endurance events, the body may also utilize fat stores as a fuel source.
the job of fat cells is to store fat in the body until it is used for fuel
No, fat is not a fossil fuel. Fossil fuels are formed from decomposed organic matter over millions of years, while fat is a nutrient stored in the body for energy.
